I am currently trying to make a field test device to evolve our PoC. I am having issues with sleep (I am just trying to have a stop mode sleep for 15 minutes, wake up, send a reading, go back to sleep)
It is powered off a USB external battery. I want to turn the lipo charge circuit off all together, as it flashes an amber LED when in sleep.
How do I disable this charger/amber led, and are there any current examples for successful sleep with the network either staying on or turned back on after it comes back on??
